I Original application filed April 4, 19257, SieriaIwNo; l i 192e.'serial No. 109,608.

fffTlie'present invention is i an improved lchlaplet for usein moldingto prevent displacement of the core in kmolds ory molding flasks. l

The object of the inventionis the produc ltion of amore durable chapletgiving'more support and strength thereto, due toits par-k ticularconstruction, as a consequence rendering the `chaplet compact, evenlybalanced, and utilizing all materialiof the blank yfrom f which it'ismade.

` In the y drawingshwhich embodiment oftheinvention as atepresentl Theinvention further resides in the sundry details `of construction,combination and arrangement of parts shown and described,

and pointed out in the appended claims.

In this specification and the annexed drawings, the invention isdisclosed in the forminl whichit is considered to be the best, butthe-invention is not limited to such form because it is'capable of beingembodied-,in

other forms; and it is to be'understood that Y in .andby the claimsfollowing vthe descrip- `tion herein it is intended tofcover theinvention in whatever'form it may embody within the scope thereof.

Figure 5 is a horizontal sectional view of the modified ehaplet shown inFigure e, and Figure 6 is a perspective view of the chap'- let. Y

yReferring particularly to the drawings, in which like charactersvdenote similar and like vparts referred'to in the specification, andreferring particularly to Fig. 1, 8 indicates an elongated rectangularblank of desirable width and lengthto provide the chaplet shownfin Fig.2, which is substantially square. n

The blank 8 is cut or otherwise formedto produce at its long side edgesthe outwardly oppositely projecting portions 9, which are located at amedial point of said edges and ultimately form ther wing iianges whichGHAP'LET knon. nonnina. fr

and-1n to llie at right anglesbetweenthe top and bottom plates llOand11, and te ,form struts extending transversely across the latl v.terfrom'the rear edge toward the front edge thereof for .ably greaterthanone-half the width of said a distance at least, but prefer-FSU plates,as illustrated in Figures v'fand 5 where the free endsiof`rstruts"terminate at a point adjacent the front edges of the. plates 10and 11. yThe outer or free ends 14 of S5 bent on lines s and t, respectively, to extend at anyl desired anglejto ythe body of said struts`9,rforthe purpose of giving additional srength to the flanges or lstrutsand to give support to the'plates 10 and 90 11 in the direction oftheir length and atl their front ends. As shown in Figures 2, 3,y and 5,it is ordinarily preferred to extend the end port-ions 13 to be out ofalignment with the upright 12 and 12ZL so as to give 95 `support to theplates adjacent their side edgesand to avoid obstructing the passage of`molten metal between the struts 1 or flanges9-` ,y

From the foregoing it will be observed that ,chaplets of greaterdurability and strength are provided, using a minimum oi" v stock andbeing compact in construction and well'balanced. Manifestly with thepresent construction, a chaplet of any desired size y can be made' froma single strip of'material withk winged flanges or struts extending be-vtween theitopr and bottom from therear to the front thereof, withoutincreasing'the width or area ofi the top andbottom plate, iA

Having thus described the inventiQnmwhat I claim as new andv upon whichit'is desiredY -f to secure Letters Patent, is:

1. A chaplet comprising top and bottom a substantially straight uprightconnecting the plates at one edge of the latter and extending at rightangles thereto, the outer side edges of saidupright having laterallyextending winged flanges thereon extend-ing at an anglel thereto andbetween sai-d plates, said fianges being of a width to extendsubstantially across said plates.

2. A chaplet comprising top and bottom plates, a straight uprightconnecting said plates at one edge thereofand spaced from struts formedby iianges on the opposite edges of said upright and extending atsubstantially the uprights and lying between said plates, the free endportions of said ianges extending in an angle to the body of the struts.

3. A chaplet comprising top andbottom plates,'an upright connecting theplates at one edge of the latter, the outer side edges of 4said uprighthaving laterally extending winged 'flanges thereon extending at anangle. thereto and l'between said plates, said flanges being of a widthto extend ksubstantially across said plates, said upright beingperorated.

4. A chaplet formed from anelongated blank of sheet material, the medialportion ot the longitudinal edges of the blank each having thereon alateral extension, the marm ginal end portions of the blank lying insuperposed"relationte-providevtopand bottom plates, the top and bottomedges iotsai'dx.

-tensions continuing into the blank by slits, said extensions .continuedbetween said 'plates whereby the extensions lorm struts extending fromthe back yedgeotV thegchaplet to a point adjacent the front ledge.thereof;

5. A chaplet formed from an elong-ated blank of sheet material, themedi-al portion of the longitudinal edges ofthe blank each havingthereon -a lateral extension, the mare. ginal end portions of the blanklying in superposed relation to provide top and bottom plates, saidextensions extending between said plates whereby the extensions formstruts extending from the back edge of the Chaplet to a point adjacentthe front edge thereof, the medial portion of the blank forming theupright having an opening therein.

6. A chaplet formed from an elongated blank o'l sheet material, themedial portion of the longitudinal edges of the blank each havingthereon a lat-eral extension, the mars ginal end portions of the blanklying. in superposed relation :to provide top and bottom plates, saidextensions extending .laetween said plates whereby the extensions formstruts extending romthe bac-k edge of the c'hap'let to a point adjacentthe front edge thereof.
